Quoted from frolic:I think the scream only works when loud. If it wasn't loud, you'd just be sitting there watching another animation of a ghost. It would have no impact.
This means mine will be "off" most of the time, but when I have a full house of people, it's sure going to be turned on.
Does the scream only happen in-game? Or in attract as well?
Best case would be a separate volume for scare/attract. Second best would be that it follows volume set for the game.
